Problems solved by technology

[0005] Additionally, due to their rigid nature, conventional exoskeletons are not comfortable and ergonomic for the user and do not provide complex movement
For example, given their rigid structures, conventional exoskeletons cannot provide complex translational and rotational movements of the human body, but only basic hinge-like movements
Therefore, the possible movements of conventional exoskeletons are limited
Also, conventional exoskeletons usually do not share the same axes of rotation and translation of the human body, which can cause discomfort to the user and may cause joint damage in case of prolonged use of the exoskeleton
[0006] US 2018 / 0098907 and US 9,827,667 disclose related systems and methods, but are complex and / or lack flexibility and / or lack devices for biofeedback

example 1

[0345] Figure 1 and 2 Illustrated is an exemplary embodiment of a soft exoskeleton 1 of the present invention in front of and after the perspective. Figure 3 and 4 be Figure 1 A depiction of the front perspective, where only the selection of components is shown.

[0346] Soft exoskeleton 1 includes a control module 4, the control module 4 is provided with a plurality of actuator connectors 41 and signal connectors 42, a plurality of artificial muscles 21, 22, 23, 24 via actuation connection 27 connected to the control module 4 actuator connector 41; A plurality of signal modules 61, 62, 63 via a signal connection 67 connected to the signal connector 42 of the control module 4, a plurality of anchoring elements 51, 52, 53 including a belt 51, two artificial patella 52 and two shoes 53, and the fascia network comprises a plurality of fascia connections 31, 32, 33, for connecting and / or supporting muscles 21, 22, 23, 24, actuation connection 27, signal modules and anchoring elemen...

[0360] Figure 6 Is a perspective view of a first exemplary embodiment of muscle 22 of the present invention. Figure 5 and 7 Is a perspective view of a second example embodiment of muscle 22 of the present invention. therefore Figure 7 Is an exemplary perspective view of muscle 22 of the present invention tendon 221.

[0361] Single-articular muscle 22 includes a single elongated muscle core 223 extending between the first tendon 221 as the first endpoint of the two endpoints of the muscle 22 and the second tendon 2222 as the second endpoint of the two endpoints of the muscle 22. Thus, the exemplary embodiment illustrates a case in which a single joint muscle 22 extends between the corresponding first non-shared tendon and a second non-shared tendon pair (221, 222), but the present invention and the muscles according to the present invention 21, 22, 23, 24 are not limited thereto. Specifically, Figure 5 and 6 The muscle 22 may preferably correspond to the location of the user's he...

example 3

[0376] Figures 8 to 10 Exemplary embodiments of the signal module 62 relate to the present invention. therefore Figure 8 is the front view, Figure 9 is perspective, and Figure 10 is a perspective view of an exemplary embodiment of the signal module according to the present invention when worn by the user.

[0377] In an example that may be combined with Example 4, also referred to as a signal module distribution of nodes having at least one electrical input / output from another signal module or from a backpack. In this example, each signal module has four sensors.

[0378] In the example may be combined with Example 4, further, all muscles are connected to the signal module. Thus, the signal module provides data and power for the relay of the backpack. Thus, some signal modules (e.g., upper and intermediate signal modules 61, 62) are connected to the artificial muscle.

[0379] In this example, each signal module can be connected to up to four artificial muscles.

Abstract

The invention relates to an exoskeleton and an artificial muscle for a soft exoskeleton (1). The muscle (21, 22, 23, 24) comprises: a first (211, 221, 231, 241) tendon and a second (212, 222, 232, 242) tendon, each comprising attachment means (227) for attaching the muscle to a muscle connector (32) of the exoskeleton (1); and a muscle core (223) extending between the first (211, 221, 231, 241) tendon and the second (212, 222, 232, 242) tendon and made of a deformable material, the muscle core (223) preferably comprising an outer cannula (225); wherein each of the first tendon (211, 221, 231, 241) and the second tendon (212, 222, 232, 242) is adapted to receive a respective end of the muscle core (223); wherein the first tendon (211, 221, 231, 241) preferably comprises an actuation interface (229) for connecting the muscle core (223) to an actuator for generating an actuation; wherein the muscle core (223) is adapted to undergo a change in length when actuated such that the first (211, 221, 231, 241) and second (212, 222, 232, 242) tendons move towards each other when the actuation received via the actuation interface is open or increased and away from each other when the actuation is closed or decreased.

Description

Technical field [0001] The present invention relates to artificial muscles for exoskeletons, exoskeletons and methods associated with exoskeletons. Background [0002] The exoskeleton provides a structure worn on the user's body, which is actuated to induce or support the user's movement. For example, people with spinal injuries who cannot control certain parts of the body are able to use this exoskeleton to enjoy movement. Additionally, able-bodied people are able to use power exoskeletons to enhance their abilities, including increasing endurance for walking, running, or working, and improving their ability to lift or otherwise manipulate heavy objects on the work floor, in a professional or personal environment, increasing or optimizing load capacity and load. In this environment, exoskeletons can reduce and / or prevent problems associated with employee injury, reduced productivity, and absenteeism. Moreover, exoskeletons can improve ergonomics, optimize ROI of human capital, a...
